yes. FWIW: Smarty-2.5.0 behaves differently than 2.6.2 does: with
use_sub_dirs=true it behaves like 2.6.2, but with use_sub_dirs=false
it behaves as you propose: no crc32-numbers in the
compiled-template-name, but something like ^full^path^to^template.tpl .

I like the behaviour of 2.5.0 more than it is now and would like to
see it reverted.
