So try fixing broken links -- which post revision has the bad link? Search and search through many MB of old records just to find 1. Repeat process several hundred times. Dump author posts. Is it fixed? Run site map utility. No. Repeat until fixed.. DAYS later.
And yes Google for one does indeed try to index all the revisions - not only does your site now have a massive number 404s, but broken links are everywhere the search engines and spiders look. So of course your site gets demoted. I'm sure the corporate entities using WP will simply adore this aspect of this so-called (developer) feature. If other single users were asking for post revisions, I doubt they had this version in mind.
Then of course, the author (admin) who fixes posts other than his own, now owns the revision. If the admin goes away (is deleted) for what ever reason, then so do all the fixes and the original author's post reverts to the original broken links and all.
My host only allows a small fixed-size MSQL db, as do millions of other WP 'ordinary' users. Won't they be surprised when they exceed the host limits! So how many of them are going to hand edit their dbs? Zero. Time to look else where for another system, even if it means going back to hand html coding. Nice feature? Not! Refusing (wontfix) to even entertain the idea of fixing revisions with on/off switch, is the height of arrogance.
As for the customer service/support, if this board is any example of what to expect from WP developers (and certain other arrogant and abrasive WP bigwigs) going forward - ie the aforementioned rudeness and arrogance, it is time for someone very high up to step in and replace the current "support" team with one more customer friendly.
This whole affair is like APPL telling its customers that the next version of MacOSX will no long use a GUI, move to a Linux interface telling customers to learn to use the Terminal from now on.
Eventually more and more people will either revert to older versions or find another system - systems which, picking up on the arrogance found at WP, will listen and supply some better product. WP will fade. The price you pay for refusing to listen, for minimizing your customers concerns.
I, for one, am sick of this schtick from WP personnel, and DO plan to eventually move on.
Yeah, I can hear it now ... WP: See ya!
