At least it would be nice to get a warning when opening a file with missing fonts as a first step.
And manual kerning should be removed if the font was replaced.
I think this problem has two parts. One is a bug (user doesn't get feedback and original information is silently discarded) and the other can be a nice feature addition in the future (the font alternatives dialog).
IMO the "bug" part should be addressed as soon as possible.
