Is there no synchronous version of Signer.signed_attrs() ?

[sbkis]

Hey. I'm wondering if there isn't a synchronous version of Signer.signed_attrs and if there isn't how come this decision was made given that there are sync/async counterparts on most other methods. This one is async but doesn't have the asyncprefix on the name like other async methods and it looks like it was made async in 0.9 in a breaking change. Am I missing something here?

Any reason why you can't use asyncio.run(...)? Virtually all the synchronous methods in this lib are defined as compatibility wrappers for their async counterparts like that. If a synchronous implementation of signed_attrs were ever to be added, it'd be that kind of one-line wrapper. In other words, you might as well write it yourself, since the restrictions on asyncio.run(...) would apply either way.

As for the rationale: it's been several years (almost 3 years to the day, it seems!), and I honestly don't remember the details, but when I planned out the transition to async-first, I decided to provide compatibility wrappers for methods that I expected to be called within client code.
Not for everything, because it'd eventually result in a lot of never-removable code that presumably very few people would ever use--this was even more true 3 years ago than it was today. Also, the synchronous wrappers have not really been kept up-to-date API-wise anyway.
