After finding out that I cannot file SPR's directly (It has to go through my reseller, which is very friendly and helpful, but I have no further influence). And after observing that no attention is payed to these SPR's whatsoever I stopped bothering. I try to find workarounds and share these with fellow users.
The enhancements for 4.0 are indeed not very exciting, last year October it looked better than this, so they've decided to do less.
You are right about maintenance, I will stop it, I am sure PTC won't notice that either.
