The wiki would serve to advertise each projects interests, and if some 
other project has a common interest, they could get together to 
standardize it in the interest of both projects?

IMHO, libnotmuch should stay focused on the core: indexing and tagging, 
avoid becoming bloated by staying minimal, doing one thing well. Else, 
it would not deserve the "notmuch" name anymore!

However, maybe this could be in some extras, maybe a separate 
notmuch-extensions library.

I'm too new to libnotmuch to answer, maybe other people have an opinion?

For messages with a plain text part, I'm taking the first 100 chars. If 
there's no plain text part but an HTML part, I'm using some random 
html2text library (https://github.com/Alir3z4/html2text) and take the 
first 100 chars.

Here's what we could add:

As a general rule, an application MUST prefix their own property names 
with "x-<project>-". It is recommended to report an application's 
properties on the notmuch wiki, to open collaboration with other 
projects having common use cases, ultimately opening to standardization 
outside a project's namespace.
