Here is a comparison of the installed sizes of the TeXLive packages (I
took the info from https://packages.ubuntu.com).
package bionic (18.04) focal (20.04)
------------------------- -------------- -------------
texlive-base 52MB 73MB
texlive-binaries 36MB 36MB
texlive-fonts-recommended 18MB 15MB
texlive-font-utils 4MB 4MB
texlive-lang-cyrillic 40MB 40MB
texlive-metapost 2MB 3MB
texlive-plain-generic 53MB 56MB
texinfo 7MB 11MB
texi2html 2MB 2MB
------- -------
214MB 240MB
This doesn't explain the difference of 160MB... I don't have enough
time to do more size comparisons, sorry.

The gs version coming with 20.04 (9.50) should also guarantee small
PDF files of the documentation...
