For the services I mentioned, I don=E2=80=99t feel that lack of first-class endpoints is a hindrance in terms of flexibility. We=E2=80=99re trading expressivity for ease of use. > I understand that copypasting all the fields into Guix records is a bit > of a non-starter, but I don't think it's a good idea to simply give up. > I just need some pointers in which direction to continue. Like I wrote, I=E2=80=99m kinda skeptical about the idea. :-) Now, if you find good motivating examples and find a way to express endpoints that remain concise in common cases, that may be more appealing to me!
