Yeah, using a direct SVG is currently not ideal for Wikipedia unless
someone manages to make a much more lightweight SVG version of the logo. :(

Possible yes but it would change the skin layouts more dramatically and may
break customized skins/CSS.

"Fun!" :)

On the plus side, the $wgLogoHD setting would work fine with both the
background-image method currently used and a possible switch to
<img>+srcset in the future if/when we're willing to make bigger skin markup
changes... so we can adopt this first and then do skin cleanup later.
