This seems rather cold (I wouldn't presume that the described usage is
actually bad for the users, not having seen the program in question),
though assertion is technically correct (if users are at odds with
development of a technical report, users come first). I would point out:

It may be cheap for the developer to use synchronous mode, but it's not the
UI event loop works, and as such it's almost always a bad proposition for
the user. It's not a sustainable coding pattern (what if you want to listen
for two operations at the same time?), it's generally a hack all around. It
doesn't negate the need for your application to perform sanity checks like
"Is the data loaded? Does performing this operation make sense?", even if
using synchronous mode *seems* to let you avoid such checks.

Maybe there's another reason: Good idea or no, removing this feature DOES
break reverse compatibility with the de-facto behavior of many Web
browsers. I'm not sure that's reason enough to standardize on the behavior,
though. However, it may be enough a reason to file a bug report if the
behavior ever breaks (though if they come back and say "it was never
standardized behavior to begin with, you shouldn't have been using it in
production", I can't really blame that either).
