I find your wording very ambiguous : ban or discouraging ?

I also see 3 typical use-cases that you mix up and that finally
make your proposal difficult to approve as a whole .
It is probably better to tackle the first 2 points first,
not forgetting the lack of diversity in both discussions and votes
not to mention votes "for the principle of the proposal" and not
necessarily for the proposed form

- "completed depreciation" : data, known preset(apps have
been migrated to the new tag.
ex diaper -> changing_table
there is no sense to say on the diaper page "any tag you like".
of course it's a right, but it makes no sense. (we could also
add a banner to every page said the same thing again and again)
A new contributor has no interest to use the old tag, a user of
the data either.
If someone would propose a better wording or even a 2nd template,
I find the idea relevant.

- the "imperfect or incomplete" deprecations: sometimes approved by a
vote, sometimes the presets of the 2-3 main editors have been modified,
sometimes known datauses use the new tag but data have not finished
migrating.
this require all apps (and thus also contributors) to take into account
the old scheme.
Here again the banner is not very well formulated. it should focus more
on the current situation (it is deprecated the switchover isn't finished
and the old tag must still be taken into account for the use of data)
A too long transition period is often very confusing, which is not
beneficial to anyone.

- the "duplicate" tags not depreciated :
yes phone + contact:phone is an issue for datauser (what does phone=1
contact:phone=2 mean ? either it's the old and the new number, or it's 2
no valid, impossible to know automatically, you have to read the history
and hope for a clear changeset message to understand)
But the community does not have a majority opinion on this issue. Saying
over and over that it's a problem doesn't really help: either people
agree that there is a problem and saying it again doesn't help, or they
disagree and saying it again doesn't change their minds.
