Comment 20 for bug 1840560

Changes tested for SRU to Impish, Hirsute, and Focal.
(Let's skip Bionic unless there's a strong necessity.)

The results are equivalent on Impish/Hirsute/Focal.
(hwmatch error line no longer present.)

...

Since the changes are low impact and low priority,
let's just stage them instead of pushing SRUs now.

Only the MR for Focal could be submitted since MRs
in LP can't create new branches / need an existing
branch, and both Impish and Hirsute would need new
branch in the package's git repo so only Focal has
a MR proposed (that mentions this + pull requests.)
