Question: How to adapt RPSL for this?

Solutions:

1) Change the definition in RFC2622 to

<as-number> An AS number x is represented as the string "AS[0-9]+ or AS[0-9]+.[0-9]+. (In other words, follow the Michealson draft).

2) Other? If so, what?

It would seem sensible to follow the draft rather than create confusion by trying something different. Of course some implements may not have a bounds check on the max size of an AS number.

But they may consider it to be an integer and the new syntax will be x.y. cheers denis

Is it worth doing another update to RPSL to include this and some other low hanging fruit?

Mark.
