Me, I'm a software developer too, "only" for about 10 years.
In all point I can agree with you!
I would like to say my thanks for a well done job too!
My interest in genealogy is old, but I began spending time to this interest only some weeks ago. When starting to seek in the internet for a good genealogy software I was astonished about the amount of software products concerning this theme. I tried only a few product that I found accidentially, befor I got PAF (188.8.131.52).
I was astonished about the power and quality of a tool that I got for free!
Better than that I appreciate the good and accepted GEDCOM standard!
But there are still some questions.
How will the support work? Can I expect support for a free tool? (There is a german wisdom in the sense like "Don't look in the mouth of a horse you got donated.") Where can I get informations about future releases? Where can I get informations about known bugs? Is PAF the "best"? Where can I find a good, neutral comparison of genealogy tools?
