I remember various attack vectors.  They're not necessarily trivial
to exploit, but it's still problematic (which is likely why it's
disabled by default in Debian's build).

I'm talking about xclip-mode, not xclip.

xclip-mode also has code to support wl-clipboard (I never tested it, tho).

It has its advantages, of course.  But also its downsides.
The overlap with xclip-mode is fairly large, tho.
