I’ll join also the support of a sample, but I wouldn’t go for random. Going back to the study that Nama did (with bits of help from me), we started from the analysis of the planet file to have classifications of participants, then used the username to invite people through mapper-to-mapper communication. The reason that you need to follow a more stratified sampling is participation inequality (that’s why I’m going on and on about it - https://www.ubiquitypress.com/site/chapters/10.5334/bax.c/ ) – because there is such a tiny group of heavy contributors, without a targeted sampling, it’s very likely to miss them…

I want to second Thomas here. To avoid unwanted biases the best would be to send out an e-mail to a random sample of all registered mappers. In case, we are only interested in active mappers, we could limit this to a somehow defined active mode (e.g. 'has mapped at least once last year'), but still should approach them by e-mail. I cannot tell, however, whether this would conflict with OSM's intention or some national laws not to send out unsolicited e-mails.
I want to offer to volunteer drafting a survey as well, if needed, as I already have some experience with academic surveys.

That is an interesting idea of putting notices for a survey into the
desktop editors. However, I don’t think that would be my top choice if
I were to design a survey for OSM.
I think that surveying a random sample of the population is extremely
important. It is important not to risk introducing unintentional or
intentional biases in the survey.
My naive assumption is that a survey advertised within the desktop
editors would result in a higher participation rate from advanced
mappers and from OSM users who maintain more active ties within the
community. It would difficult to measure and correct for these biases
(and potentially others). In addition, this could introduce issues
with the validity of the results.
We need to be wary of designing surveys where people self-select
themselves to participate.

The main problem with this (again broken record mode) and really ages
old issue, is that we do not ask sign ups for permission to send them
unsolicited mail in any form.
The problem is not terribly difficult to fix, just nobody that has
proposed to do a survey (and there have been dozens and dozens over the
years) , has actually had enough interest to either fix the issue
themselves or pay somebody to do so.
If a survey should be answered by active mappers, notifications in their
editor would be a way to reach even more than using third-party news
services like Wochennotiz and WeeklyOSM. JOSM has a message of the day
feature as long as I can remember. iD is usually used from osm.org, i.e.
a message (top left corner) on osm.org for logged-in users could reach
mappers using iD. This would also reach users who use Potlatch 2. Only
mobile editors are not reachable. I myself think that popus with the
latest news are more annoying than helpful in mobile apps.
To summarize it, we can reach mappers using desktop editors already.
There are only two groups which are unreachable: mobile-only mappers and
inactive mappers. If I were an inactive mapper, I would find it annoying
to get an email asking to contribute to a survey.
