Disadvantages of offering and maintaining 2 different styles:

1. uses more disk space on tile servers
2. uses more time to render tiles (i.e. slower updates, or more hardware
required)
3. harder to keep styles current when making improvements

Your use case of "easily recognizable tertiary road in sparsely
populated regions" is valid, but perhaps it is "niche" enough to accept
that it need to be served by the main map style.

I'm in favour of the change simply because it is a change.

As a project, we must take great care not to ossify. Humans are
inherently change averse; most people prefer "the same as yesterday"
most of the time. If we allow the project to become too averse to change
then we'll never see progress. (What, API 0.7 you say? Just when I had
0.6 hardcoded in my 37 applications, no way!)

This is not change for change's sake (although if it were my decision,
I'd even be tempted to do that just to keep us alert) - this is a well
thought out suggestion and I don't see why we shouldn't, after all these
years, do something else, colour-wise, for a while.

Bye
Frederik
