Well yes, but actually no.

On a more serious note, most things are available, some things are behind on updates unless you compile everything yourself (even when using the ports collection).

I haven’t used it as a desktop environment, I was just maintaining a FreeBSD server, so no idea on that end

Continuing on a squash merged branch is very annoying, and I had to deal with this in one repo regularly… Luckily I was annoyed enough to research about this and found out about rebase --onto "main merge commit" "branch merged commit".
