There's a NOTAM code specifically for stand closures: QMPLC. It's used worldwide, not just in the UK. You can petition ICAO if you like...

But as you say, it's not the detail of that that is important, it's the principle. Let me try to persuade you one more time.
NOTAMs are
not just intended for getting information to flight crew, they are for distributing temporary aeronautical information to
everyone with a need. In the example that you cite from cubflyer, if the airport operator wants to tell the aircraft operators and local ATC that a stand is closed, it should do it by NOTAM. The fact that you or any other pilot doesn't want to know is irrelevant.
NOTAMs are meant to be passed from AIS to AIS. It's up to the AIS to provide an appropriate pre-flight bulletin for pilots' use. Different users have different needs -- what you've got on your web site is
spot on. A different sort of filter is required for each group. I don't understand how you and Mike can write stuff that is so clearly sensible on the site, and then post a message here that makes it look as if you think the entire NOTAM system revolves around not just flight crew in general, but GA pilots in particular.
Isn't it obvious that the place for filters to be applied is at the point of delivery? It's the classic use of a database: put
all the information in in a structured way, and take out
only the information that's required at the point of use.
What you should care about is not whether QMPLC NOTAMs go
into the system, but whether they get churned out in
your PIB.
You have the opportunity to help make that happen right -- good luck on Friday.
