Ah I didn't know, that's interesting! Now that you're speaking of this,
I'm pretty sure we have somewhere and old HTTP client made to retrieve
config files that's also 1.0 only. Often clients that speak 1.0 are
those which want to advertise that they will *not* parse chunks and
will instead consume data after the empty header till the end of the
connection.

In the IoT world it tends to be awful, with code trying to imitate HTTP/1.1
using strstr() and consorts to find the relevant minimal parts :-/ Quite
frankly it would be cleaner to stick to 1.0 sometimes!

We disabled it by default 5 years ago in haproxy and didn't get any single
complaint (except from the usual developer complaining that "GET /" on
telnet now returns 400). So far so good :-)
