Out of curiosity - is it "safe" to install all new packages from cssu-thumb repo now, or we need to wait for a sign?

I'm asking, as I have certain device that wasn't updated for a year or so, and for various reason it need to have mp-fremantle-community-pr package removed. Thus, I'm wondering if it's worthwhile to painfully install things from thumb repo with =version_string, or everything should "just work" now.
