The concept of sharing a data schema across multiple applications is a tough one. Invariably, your schema gets compromised for performance reasons: denormalization, which indexes to create. If you can cut the size of a row in half, you can double the number of rows per page and, likely, halve the time it takes to scan ... |
Your objection is assuming that the issue was the invitation was going to the spam folder. You don't know that for sure (or, at least, you hint at such).
