Harry, let me assure you that Thomas would never toss a module for no reason and he would never screw things up.
I have quite a large config with some whistles and bells and maybe a couple dirty hacks in it and I use Archlinux (which means bleeding edge, constant updates and such), I think the first version I tried was 2.5.27, and not a single feature was broken with an update. He also maintains one of the most detailed and accurate manual pages I've ever seen and runs forum and mailing lists where he is almost the only person to come up with a working solution to quite tricky problems. So if tomorrow Thomas says 'OK guys, I think I'm rewriting fvwm in Lua and I think I'll toss this and that modules (including their functionality into fvwm itself)' my reaction would be 'Go ahead and thank you for the great work!' //I also appreciate all the other people's work on fvwm!
