Comment:

 I have not looked closely at the patches but for now we don't need
 {{{
 334690 Isolate AlternateService mappings by Origin Attributes
 1334693 Investigate and isolate SPDY/HTTP2 state by first-party domain
 when privacy.firstparty.isolate = true
 }}}
 .
 We have H2 and SPDY still disabled and will have to audit it first for
 other issues. We can then apply the backported patches (if we get to that
 before esr59).

 As to the patches with substantial conflicts: we would want to have those.
 (Or write our own).
