I tend to agree with your point as shown. Every inch given to 'worthy causes' like Delta.chat can come with the cost of unscrupulous types like scammers/spammers. I don't really expect Gmail to bend over backwards to accommodate this. Like you though, I worry that this could inhibit Delta.chat getting enough critical mass. On the other hand, if delta.chat starts to collect some critical mass, Gmail would probably want to avoid the generation of a pro-tip like "don't use Gmail, they're too restrictive, use Fastmail/iCloud/Outlook instead" because that could cost market share...or they can increase that limit a bit and keep the status quo going well. Full disclosure -> I am not a Google employee, but thank you for providing the caveat for your comment! Those tend to help comments be read in a more meaningful light, speaking for myself at least :D
