The users should really seriously consider upgrading. 5.3 is EOL for a year now (which means, not even security fixes for a year) and 5.4 is going EOL in 2 months. If any of these sites are public-facing (and due to the nature of wikis, many of them, to some measure, are), running out-of-support software may not be that good an idea.
If this is all their host provides, however, this will in practice lead only to never-updated MediaWiki running on never-updated PHP.
