For people who are reasonably happy compiling code, it's probably not so 
much of an issue. The annoying part is that some LTS distros (Ubuntu, 
I'm looking at you) are still shipping GEOS 2.2 series, even though 3.0 
had been out nearly a year before the distro shipped. So for these 
people we still need to maintain 2.2 series support IMO.

I wouldn't mind this so much, except for the fact that 1.3.4 contains 
critical memory leak fixes/crash fixes that people really need to have 
in production :(  However, for 1.4 I have no objection to making GEOS 
3.0 a minimum requirement - this would at least enable us to get rid 
those final compilation warnings. Feel free to put forward a proposal on 
-devel :)
