indeed, changing more than one thing at a time..

OTOH, as a co-author of R 4.0.0 which I have been using in
its prereleases for many months with ESS,
I have never noticed different buggy behavior of ESS between it
and R 3.6.x

But I do observe bad ESS behavior, something bringing emacs to a
crawl or having to kill it... I think it is related to running
several R sessions (in several ESS buffers) and several [M-x
shell] generated shells inside the same ESS and partly having
many lines (100'000s) in such buffers.

I strongly suspect it is related to the (mis)feature that ESS is
monitoring things not only *R* buffers but also in *shell* buffers.
.. I think part of current modern ESS work under the assumption
the ESS user is working on *one* R project / package at a time,
rather than as me, compiling R, hacking R, hacking 3 different R
packages all in the same emacs instance.
