Having a custom column works fine but is no more or less work then selecting and removing the tags after import. If you import 100 books, select them all and remove all tags with one batch metadata edit, check a box to remove all tags and click OK.
That said, I might move my collection creation to Series and a custom genre column and let the tags run crazy.
