I concur - the model ought to be that log files aren't writeable
in the conventional sense, but append only. For installations where
one worries about security this might even be enforced with chattr
at the filesystem level (ie not just convention).
Using a pager is also more efficient - pagers are simpler, faster and
don't risk accidentally modifying the file. Depending on
editor a harmless update can involve a rename() aka mv, in which case
subsequent log entries might be lost.
If (any of) you still prefer to use an editor, consider invoking it in
read-only mode. Eg "vim" can also be invoked as "view"
