We don't modify the libical up till now.

There're 3 reasons from my side:

1. Libmimedir don't support all the properties provided in RFC2445.
For example , the properties: organizer (4.8.4.3), the recurrence id
(4.8.4.4),
Exception date/times(4.8.5.1),  exception rule (4.8.5.2), ....

These properties are very important properties. I don't know 
why libmimedir ignore them.

2. libical provides interfaces to check whether a component conforms to 
RFC2446. If the compoennt pass the check, it's ready to be send out.

In libmimedir , I havn't found similar interfaces.

3. libical has been used in quite some projects like : evolution , KDE
PIM 
calendar. It has been proved to be mature and stable.

Are there anything more?
:)

Yes , it's true.  Libical can't handle vCard type.

This is really a problem of libical. Some forks for the project 
are got absorbed into the KDE and GNOME calendar projects.
And the original project hasn't be updated for a long time.
