It's fine, the more assets the merrier, zero friction to switch them to BTC later.

Besides, stablecoins are useful, no need to be all in all of the time.

Finally, might actually increase lightning usage a lot, because of better privacy vs other USDt solutions (even on liquid) and lower fees.

Honestly I don't see what's not to like. Those who want to use USDt will use it with less friction than before, and for those who don't, well, nothing changed.
