As I can conclude from all the answers earlier, then still my only option if I want my ip transit provider to be able to advertise some /48 within my /32 at random times and for random durations is using /32 as route6 object and hope that everyone in the internet filters "2001:1234::/32 le 48 permit" or "2001:1234::/32 eq 48 permit" instead of "2001:1234::/32 permit"? Or actually make the 65536 route6 objects (for each of the /48 that fits into that /32)? Or is there a third possibility instead hoping that AS-s from all over the internet are familiar with this kind of issue and allow /48 prefixes into their routers instead of exact /32 prefix (although the route6 object states that our provider should advertise only /32) or making unnecessary amount(65536 objects for 1x/32) of route6 objects?
I think you missed my point that there is no way you can ensure that A Random Network out there will accept any/all /48s from your /32. Router memory is costly, and deaggregation eats up costly memory to the point that people are forced to decide between "I need to buy a new router, to carry someone else's deaggreated prefixes, which I'm not paid for" or "just drop /48s, lots of money saved". Your transit ISPs are paid by you to accept and propagate what you agree between each other. Most other parties are not contractually bound, and as such, free to do what is reasonable for them.
