What if you build a browser using libcurl for the networking parts?

I expect no one thinks we should conflate anything, but I'm pretty sure a
large amount of curl and licburl users think we should offer the same or
similar transfer features that the browsers have.

We offer options for users to opt-in and out of features, both at build-time
and runtime to allow them to decide as much as possible.

Sometimes they do, sometimes they don't. curl and libcurl offer users to make
those distinctions rather than us doing them for them.

Browser-like automation is a pretty signification chunk of curl use cases.

I must have missed all your pull-requests and work into improve curl's HTTPS
record resolving without using an external library.

Linking with libcurl is already "inheriting significant structural
complexity". The key is probably to provide value that is worth more than the
complexity it contains/hides.
