I don't agree. XSLT version works and it's still useful for
transforming osm - svg in browser or for making custom maps. Setting
up orp might be too dificult for some users. The only problem I see
with XSLT is performance and memory consumption.

That's probably true. XSLT 1.0 is really limited language, you have to
use recursion too often. XSLT 2.0 is much more practical but
unfortunatelly it's not widely supported. Only open source project
supporting XSLT 2.0 I know of is saxon.
