This should be easy to explain and clear up, but I have to ask, as I don’t see
anything about it in the document: what deters entities from using this with a
short deadline time in order to get expedited delivery, when they don’t need
it?  How does this help a network if, ultimately, every transmission specifies
a very short deadline time?


In the Introduction, please expand “BLE” on first use.

In “Terminology”, you’re citing RFC 8174, but not usng the new BCP 14
boilerplate from there.  Please copy/paste the new boilerplate.

— Section 5 —

The definition of “TU” is out of order; please move it so it’s in the same
order in the definitions as in the block.

Why is DTL the length *minus 1*?  Doesn’t that invite mistakes?  Is there a
reason not to make it the length, and to say that 0 is not a valid value?
