I help manage releases, and also frequently check memory usage on my 
various machines and often look at Thunderbird's usage. So I can 
anecdotally state I am not aware of any feature which added significant 
memory usage as you describe, nor any confirmed bugs along those lines*.

Generally speaking memory usage in the 200-800 MB range is fine, and 
it's OK for it to go up and down as usage of functions and features 
changes.

* The only two bug reports in the 68 period are these:

Bug 1567545 - 68.0b5: possible memory leak 
<https://bugzilla.mozilla.org/show_bug.cgi?id=1567545>

Bug 1581849 - Thunderbird Daemon lives after closing - Spawns many 
instances... causing very sluggish response (eats up memory eventually) 
<https://bugzilla.mozilla.org/show_bug.cgi?id=1581849>
