I understand the concern, especially if one has already bought a product that didn't keep its promises of updates (and I'm a HX Stomp user, so I know what long term upgrades means).
On the other hand, I have the feeling that Anagram is much more mature, with a very large collection of blocks from day one (much more than I would ever need), and the NAM compatibility which opens it to an inifinite and growing collection of modules.
For me, the 2 only things that really needs to be added by a software update are the ability to play Bluetooth audio for practice, and external editors.
It seems that *this time* they have really designed a platform that they will want to upgrade and maintain in the long run. Hopefully.
The only risk is that if it fails to succeed commercially, they will probably stop upgrading it. It could happen because the price is quite high, the bass specific market is tiny, and the competition is already huge. Time will tell.
