I did. Here is the result: *21 signifies the 2021 distribution, *14 the 
2014 distribution.
All tests are done with tex21.web and tex.ch from the 3rd ed. of TeX-FPC.

tex21, webmac21, maybe=iffalse
prints only 20,64,100 pages with 30000, 40000, 42062 memory words.

tex21 and webmac21: maybe=iftrue
prints all 566 pages and uses 24558 words.

tex21, webmac14, maybe=iffalse
prints all 100 pages and uses 24093 words.

tex21, webmac14, maybe=iftrue
prints all 100 pages and uses 24093 words.

tex14 and webmac21: maybe=iffalse
prints only 20 pages with 30000 memory words.

tex14 and webmac21: maybe=iftrue
prints all 566 pages and uses 24558 words.

tex14 and webmac14: maybe=iffalse
prints all 100 pages and uses 24093 words.

tex14 and webmac14: maybe=iftrue
prints all 566 pages and uses 24557 words.

To me this looks like a memory leak, either caused by a bug in tex14 and 
tex21 or
a bug introduced in webmac14.

please find the attached tar-archive that contains unchange.sh that 
creates a 14webmac.tex from a 21webmac.tex and tex.log.

happy weaving and bug hunting,
