The FAA is on schedule to adopt the ICAO classification schema by 2024. However, it turns out that the IACO has its own problems with an even larger lack of uniformity, so that's about all that is getting copied.
The most interesting part of NOTAMs is the FAA isn't solely responsible for originating the messages, which is where the lack of uniformity starts. The airport operators are in the lead and they send these out to cover their butts.
This is the likely reason the legislation, put up by at least 2 reps, died, even though that one passed the house.
I had a larger writeup but quit it because the legislators are behind the actual curve the FAA is working on.

From the latter:
On the second Tuesday of each month, FAA holds a virtual meeting for interested NOTAM Stakeholders, all NOTAM consumers or originators are welcome to attend.
