wgHTML is very dangerous and buggy module?

Hello All.

I run into the problem with wgHTML module.
At the module project page, wgHTML marked as "recommended", but I see, that
1. Tables wghtml_revisions and wghtml_pages grows very fast. I have a little static HTML files, but half year with this module increased these tables about 1Gb!
2. Appropriately grows node_revisions table. Not such fast, but grows too.

By fact, after long period with this module and large number static HTML, your database will grow up to some GIGABYTES.

Do I not understand something?
