I think that the reference makes sense as far as longevity. How often do links to a specific page change? Very often. How often do domains change? Not as often. MLA and other style guides are generally written with print in mind, not links directly to content being cited.

Sites that want their content linked, reused and cited should use some sort of permalinking strategy. I don't think we should have a unverifiable citation because a publication does not follow sound link generation strategies. Provenance of the information is what we seek, citing a journal who doesn't provide a time proof way to access the resource should not be cited.
