We've had significant complaint in Flycheck for freezing Emacs for <1s: we have a synchronous sanity check to determine whether a checker can execute in a buffer (it runs a single time, and it should be async but I haven't gotten around to rewriting it). The problem is that some programs, including eslint, can take as much 1s, and in some bad cases 2-3 seconds, to parse their own config and decide if they can even run. Users have complained about this delay. It might be better if they were able to scroll around, though — is that what happens with WISI? But if we have a fully synchronous TS, then that won't be possible either: it will be a complete Emacs freeze, no?
