I seem to remember this came from actual user bug reports, not a hypothetical situation.
So not going to happen. People *often* write minimal examples that look like

\documentclass{article}
\usepackage{fontspec}
\begin{document}
% something that may or may not involve accents breaking
\end{document}

Looking quickly into this I've decided *not* to do it at this stage. The problem is that I need to change encodings and I can't really see the point to complicate the code: I think it'd have to be something like

* load unicode font encoding (EU1 or EU2 at present)
* select OT1 again
* after the default fonts are set, select EU1/EU2
* at begin document check if the above has happened
    - if not, work out which of rm/sf/tt have been set and those that haven't been use LM
    - then select EU1/EU2

Versus, at present:

* select LM
* load EU1/EU2

If someone can make a good argument that loading LM by default is a bad idea for some reason, I'm happy to reassess this. But making the code uglier to make the internal process cleaner isn't a great idea in my eyes. Let me know if I'm wrong :)
