One of the comments on that PR (January 27, 2021) was:

We expect to be nervous about this change because of the complex area it's working in, so we will merge it /after/ the next release which should be before the Codeathon in March, but we don't see anything obviously wrong with it.

This PR was recognized as having a high risk change of regression.
The code involved is some of the most complex in Base.  (Try to
follow all of the possible paths through dbGet() )

This change was judged to be worthwhile since it actually reduces
that complexity.  Sadly, we don't get many PRs with a net reduction
in source line count.

Merging after the 7.0.5 release, and before the 2021 codeathon,
was an attempt to mitigate this risk by maximizing the amount
of testing before 7.0.6.

Unfortunately, this seems not to have been enough.
