The cases I recall are in JavaScript function calls (tal:attributes="onclick
string:document.open(${request/URL0}, 'new', 'statusbar,...')") (syntax
probably wrong), which in fact are unlikely to appear in a function call.
There are other situations I don't recall (setting values in forms, maybe),
but I'm sure it's always short strings.

Yes and also lower the barrier to entry for programmers by relying on a
common paradigm (function calls with the twist they can use paths as
parameters).
