My problem switching off of gmail is that I’d really like to start moving to an alias-based approach (so, you know,
firstname.lastname@example.org for Lemmy emails, etc.) but this then conflates two issues so I solve neither.
I wish Google Takeout were required to maintain consistent formats so people could develop tools against it. I could make a lot of progress by pulling out the decade of history I have with them and not maintaining more than a couple months of data inside their stuff at any given time.
