It's an understandable design choice, but the problem is that the email 
format (and IMAP) was not designed for this. An email is read only. 
Changing a single header requires re-uploading the entire email. Given 
how often tags might be altered then this could be extremely inefficient 
for large emails. Due dates are perhaps a bit less frequently used, but 
it's still not a very satisfactory solution.

(MailMate does have a feature which allows changing headers, but this is 
intended for more rare actions such as changing the subject of an 
email.)
