It would for example mean that people who had built PPL 0.10 for use with 
GCC, or installed a package from their GNU/Linux distribution, would find 
what they had built was no longer suitable and their distribution might 
not have a newer package.  I'll leave the final decision up to the 
Graphite maintainers; I don't think this is something that should delay 
the release, or be changed after 4.4.0 is out, so if 4.4.0 goes out with 
0.10 as the recommended version then the 4.4 series should stay with the 
recommended version being that not-cross-buildable version and 0.11 
requiring using --disable-ppl-version-check.
