Fun #BGP fact: some big carriers (at least Lumen and RETN) expect route/route6 IRR objects to match announced prefix exactly (same prefix length), longer matching principle isn't used even if you have proper ROA covering your entire allocation (IPv6 prefix with length of /40 for example) and with "Max Length" parameter set to /48.
Experienced it with one of our BGP customers.
