Browsers have refused to implement DANE for the last ten years. In the meantime, the major email players came up with MTA-STS, and alternative to DANE that cites lack of DNSSEC adoption as one of its rationales.
If you send email today, it's vanishingly unlikely that any DNSSEC will happen; email is complicated and email infrastructure tends to shut people's brains off (I know it does for me) but you can just look at the tiny slice of domains that are actually DNSSEC signed and see that there's no meaningful adoption.
I don't understand why you are being downvoted, since you are right.
For example: Microsoft has recently adopted DANE validation for outbound email, are planning to add TLSA records for their inbound email 'by the end of 2022. [0]
