The original plan was to make a final roll-up of changes and ship K19.5 shortly before K20 release (think days, not month).
That's not quite correct.
The original plan was that 19.5 should have been released months ago and we've been waiting for it to align LE 10.0.3 with it.
Then the due date of 19.5 got pushed further and further into the future and was finally completely removed - see here:

That's why we released LE 10.0.3 with latest Kodi Matrix changes (kind of pre 19.5) so you're already very up to date if you're using that and final Kodi 19.5 won't be too different to that.
If and when Kodi 19.5 will finally be released and what fixes it will contain is a question only kodi folks can answer.
so long,
