Grist is open source, Python scriptable and each project is stored in a SQLite database.
Thus I came to the conclusion that any Access database is probably better off being a spreadsheet, even with all the chaos that not having forms as a front end and not having relational structure entails. At least people can understand other peoples spreadsheets (up to a point)
In the late 90s I built some quite big things in Access and promptly regretted it. I guess Access got used for those projects because the organisation already 'owned' it as part of the Office bundle whereas Visual Studio 6 was seen as 'expensive' (I think it was about £500 per developer or something).
But these days that problem would not occur. The days of development tools needing comparatively expensive licences are over.

That's exactly the motivation I saw for Access being used in the past. I agree, those days are over and that justification for using Access is moot.
Recently I discovered https://directus.io/ which comes pretty close and it's open source.
