IMO if our current use to point to a Web page is not correct, then there is an obvious problem with the label they choose for the property in the specification.

Anyway I think this is not the case as they explicitly say "We do not (currently) distinguish precisely between physical and electronic documents..." even with the weird definition of homepage as "... is a public Web document, typically ***but not necessarily*** available in HTML format..." (Emphasis mine)

Word documents or physical paper documents as homepages?, it sounds really strange for me.

The only problem would be that we'll loose the distinction between main and help Assertors, even taking into consideration that part of this distinction could also been seen with the (optional) test modes.

Don't think so, I think that foaf:name, foaf:homepage and foaf:sha1_sum (or foaf:mbox) are sufficient and the most proper among those that are available.
