I find it beneficial to tag the sections of code that are workarounds. Later on, after a code platform change, it is easy to search through all the source code for the workaround code sections, and to review them for removal or amendment. I keep the workaround tag in the comment until no longer needed.

At start of a comment line, I use :workaround:

example:

// :workaround: . . .

You could use whatever tag you want, as long as it is not used for, or could be confused with anything else.

Hopefully, you may find doing this of benefit too.
