borg2: consider dropping --exclude and --exclude-from

In borg 1.4 there are two distinct sets of options that can be used to define excludes:
`--exclude` and `--exclude-from`
AND
`--pattern` or `--patterns-from`

To cite borg documentation:
> A more general and easier to use way to define filename matching patterns exists with the --pattern and --patterns-from options. Using these, one may specify the backup roots, default pattern styles and patterns for inclusion and exclusion.

From a user's point of view:
--exclude style seems to provide only a subset of --pattern style.
Both (--exclude and --pattern) make use of patterns - but have different defaults - which can be confusing.
It is not clear why --exclude style exists.

I just wondered if borg2 would provide a good opportunity to drop --exclude and --exclude-from and to only use
--pattern and --patterns-from, in the future. But maybe I just miss important differences between both set of options.
