I'm getting flashbacks to how 3.5 destroyed the 3rd party 3.0 supplement library.
I mean, 4E Essentials did the same thing for 4th Edition (or at least, the thankfully free errata for older books are so large that they replace pages upon pages, and even then, the newer options were not made in assumption with balance in mind with the older options).
And 2E Revised aka Player's Option did something similar for 2nd Edition.
And Rules Cyclopedia did similarly for BECMI, which did something similar for B/X, which did something similar for Basic.
And both Basic and AD&D were similar soft-reboot but mostly compatible with OD&D. Which was similarly softly compatible with the Chainmail Fantasy Supplement.
The big difference between v3.5 from 3E and 4Essentials from 4E was that those both happened like 3 years into their respective editions. Revised 5E released a decade after 5th Edition, and they've been taking it slow with 1st Party supplement releases, about as slow as they did back in 2015 and 2016. And it's not like we didn't have some of these changes in the game already – a lot of them started emerging in 2020, and the game is far closer to it's present form as early as 2022 than it was to the original 2014 form.
The great thing about the modern landscape is that digital platforms are far more central to 5E than they were to past editions, and there's multiple ways to release updated versions of both 1st and 3rd party supplements. Now, if I want to get errata worked into a print-on-demand release, that could be harder. But both D&D Beyond and DM's Guild have the capacity to update with errata at no extra cost to the consumers, if the creators and platform managers can work together to make it happen.
