It was enabled by default in the past being an internal module of trytond like

You can basically define collections of documents that are accessible and
modifiable (e.g. upload of documents as attachments) via a DAV client. 
Another (probably more widespread) use case is for party_vcarddav (CardDAV) and
calendar* modules (CalDAV). Those protocols base on WebDAV.

If you didn't use it, yes, sure. If there is a dependency on it, you will (or
should;) not succeed.

Yes, thanks.
