I imagine more people will run into similar problems as Gutenberg is installed on more and more sites.

Au contraire!

Why would people even want to try this when it is clear that merge in Core in the beginning of the 2nd quarter of 2018 is simply not happening (as we're already passed that).

More and more it seems we have nothing to worry about until at least the beginning of next year, which means a very long 4.9.x run :)

Let's focus on GDRP instead, as that actually does make a real world impact!
