You edited out my reply which addressed that:

In the open dialog, choose filetype None and you can easily open big
files, plus it will be faster as syntax highlighting won't be enabled.

For large files an auto-disable reparsing feature would work fine.

Perhaps I was wrong with 0.2s, maybe 0.5s (I didn't check Colomban's
code to see what he used).

A dialog is too intrusive. Consider opening 10 slow files and having to
click the dialog for each one. Status bar is fine - as you sometimes say
programmers don't need to be treated like newbies. Not having tag
reparsing enabled will mean a few invalid bug reports at worst.
