reqwest provides a blocking API, but reqwest also always depends on Tokio. A blocking API doesn't help when I don't want Tokio in my dependency tree at all.

I am using isahc, but that also doesn't help when (say) Rusoto AWS library pulls reqwest pulls Tokio pulls async.

I had a simple rust program that used reqwest -- it just pulled down a few web pages and parsed some data out of tables in the HTML. At the time reqwest had a simple synchronous API function that made this easy. The version of reqwest which added async support broke compatibility of that function and didn't appear to provide any similarly easy to use equivalent. Luckily my use-case went away (the website I was screen scraping died) so I didn't need to try to actually fix my program to work with newer reqwest versions. But it left a pretty sour taste regarding async...
