I see,
but contrary,
tls is only for browser?
And more,
if you kick out comp/decomp from tls,
can we be safer when we use tls?
If you know the paper, please teach me.
Or, rfc or good teacher should notify us,
"When you use TLSv1.3, you never use compression, sorry!"
I know it may be out scope,
but we have to estimate the risk.
