This is a problem with the file system, not with maildir. Here's
an example of file system (though not for Unix) that was partly
optimized to avoid these block size problems:


(just for the pleasure of citing mail from 1990 :)

Now, I would say that in general, the wasted space is small compared
to large attachments. And if you have only text and care about disk
space, you should consider a compressed format, not "pure mbox".

This depends. I index my archive mailbox with mairix, and with mairix,
it is better to use maildir as a search result is built with symlinks
instead of copying the individual mail messages.
