Thanks, but there are a few problems with this change:

While that might be the case in-tree, external packages and users might
be using that parameter -- it should stay.

The same goes for this.  I think it's certain that some external code
will be using this function, as the name is rather tempting.

I also have some further comments below:

Since you already define a replacement for `xwidget-webkit-new-session'
below that also behaves like this, is there any reason you can't use
that here instead?

I think it would be clearer to say "Jump to the page described by the
bookmark record BMK."

But I'm not good at writing documentation, so I won't insist.

Also, `bmk' should be named `bookmark', or something else to that
effect.

I don't understand why this user command has to be called
programmatically, and why it should return the URL.  Can't you use
`xwidget-webkit-uri' instead?

And thanks for the work you've been doing.  I really appreciate it.
