TODO: Check what happens with this enabled in 5.36
The other ticket is now the core implementation which is good for most uses. One advantage of this implementation here was that for troubleshooting purposes you could still see the original tokens the user typed when the user later complains it didn't produce the right results. So the new goal now would be to:
- (a) see if there's still some way to log that, and possibly optionally
- (b) see if there's a way to either:
- delete and regroup the generated activities as originally here, or
- have some way to see which ones were sent together as a single mailing.
