Part of my question may be academic but, like many technical things, it
becomes practical when getting into the details. I currently have 20 - 30
GB used by geowebcache for SRS 900913 (total for about 12 raster layers).
When a request comes in using 3857, it will not use the 900913 cache. To
use cache for 3857, I would need to duplicate the cache for each layer. It
comes down to which is used more often and if I want to support caches for
both.
I agree that I can alter the default SRS for geowebcache anytime. I would
think 3875 should be the default and we should move away from 900913,
unless everyone is still using 900913 much more than 3857.
