word-wrap wraps at word boundary that sometimes might be inside the tab name
when tab name contains spaces (tested frame-tabs.el on customization buffers
whose names contain a lot of spaces).

Sorry, I don't understand the meaning of "should".
Does this mean -nw already supports it but its support is not used?

But all web browsers truncate tab names.

BTW, is there a reason why the mode line doesn't use a variable-pitch font?

I tried a variable-pitch font for tab bars, and it looks good
and makes tab widths smaller, so more tabs fits into the tab-bar.

But maybe non-monospace fonts might complicate calculation of various
text lengths when trying to fit tabs into the tab-bar.
