For those that aren't aware: 27.2 beta 3 did likely patch an SPTM Bypass.
The advice through everything has still been "stay and wait for stuff", and that hasn't changed in the slightest
However, as there's more "known" (for lack of a better term) about this (compared to the exact specifics of the Calif chain), I would say that - if you end up in a situation where you absolutely have to update - I would highly recommend avoiding anything past 27.0.1/27.2b2 (and probably 26.7.1 for AlternateSU)
