I was planning to fix this myself, but discovered there is already a good solution available: timabell/msaccess-vcs-integration on GitHub. I have tested msaccess-vcs-integration and it does work great.

There are some forks from the original project by bkidwell, for example by ArminBra and by matonb, which AFAICT shouldn't be used.
The downside to using msaccess-vcs-integration compared to Olivers's decompose solution:
Anyway, my clear recommendation is msaccess-vcs-integration. It solved all the problems I had with using Git on the exported files.
