Ytti,
We have introduced the scalable as-set into the XR route policy language.
as-path-set does not scale well with 1000's of ASNs.
Now, you don't need to expand AS-SET into prefix-set, just enter it directly.
Example:
as-set test
2914,
3356,
end-set
!
route-policy sample
if as-path originates-from test then
pass
endif
end-policy
If this does not meet your needs and you need improvements, let me know.
Kind Regards,
Jakob.

We just recently learned of a IOS-XR prefix-set limit of 300001 when a
particular customer AS-SET expanded to a higher number of prefixes.
