There are few things to remember in notmuch development:
- notmuch is more of an evolution than intelligent design. it is hard to
do any long-planned design when writing email software...
- we all do welcome people do SMOP with notmuch and tolerate patches with
good commit messages and elegant content.
- it may take some time to get changes reviewed...
In this particular case it would be nice if someone(tm) investigated how
mu and neomutt handles these email -- and how broken (if at all) those go
if those are given large mbox file... was it so that both of those can
read mbox files...
