[Mapcss] Zoom levels: bad idea?

[Chris Browet]

Unless I'm mistaken, I understand the zoom level (as in "way|z1-11") as "OSM
TMS zoom level", right?

What about maps rendered in another projection than mercator/google, e.g.
OSGB36, which is non-othogonal ?
How is the implementation supposed to deduce the zoom level based upon a
pixels per meters zoom level?

Extreme, but I tend to think the zoom level namespace selector should be
dropped altogether in favor of the "way|s5000" indicated as example in the
specs, which is far more explicit.

While, if needed, going to zoom level from a scale in the context of a
mercator projection is easy for the implementation, I don't see how to go
from zoom level to scale consistently for "exotic" projections, given the
restrictive (assumed) definition of the zoom levels...
