They only have some of mine too, one is missing. And they've missed out a lot of versions of PandaBAS too (though I don't always upload them to the repo, as interim releases are on my own site).
A noble effort, but more care is needed. The list is far from exhaustive.
(although I still haven't fixed the issue with MrDrillux running too fast - I've been very busy and I didn't consider it a high priority because it runs fine at 200-300 MHz...)
They could probably write a daily scraper that checks the repo automatically to generate the lists... so it's quite annoying there's little software on the list. Maybe it is just early days though.
