As someone who manages code that sends out legitimate text messages for operational purposes, this is a good thing. By lowering the potential of spam situations, this will hopefully make legitimate text message sending easier to manage.
I just have a bone to pick with all this software using phone numbers as ID or notifications. Send an email where we can filter it or if you must, do an app with notifications I can tune to my liking.
SMS is almost always the one I see first, but they seem to use it as just one layer in a reliability sandwich.
Every once in a while, someone will send a text that takes multiple days to get to me, but that's about the only glitch I see.
For years, we were able to get away with email to sms addresses but they have become undependable as the carriers are blocking them more and more; likely because of the amount of spam going out.
