Yes, it actually did but only in the context of mobile devices. Moreover, 
quality is one thing and features is another.

What I tried to answer with my first post is the following question:

If we use SVG Tiny to display an OSM map to a mobile phone, will the quality 
be the same (or almost the same)?

IMHO the answer is still yes. However, I suppose that the extra features of 
SVG Full should not be sacrificed just to produce maps which are compatible 
with mobile devices as well.

Correct me if I am wrong but it just hit me that some are considering the 
option of totally changing osmarender in order to produce SVGTiny-only maps. 
Is SVG-FULL under negotiation?? It didn't even cross my mind!

If this is true, my old post might have mislead some of you for which I am
