I would argue that an all-sRGB Printer Managed Color is preferable for photographers with Epsons. The reason is that for Epson, Apple, Adobe and others the PMC workflow is considered to be the preferred consumer workflow, and as such it is fairly robust.
You can argue it all you want, when ink hits the paper, it doesn't wash. At least on my Epson's with my images and NOT with sRGB. And I prefer to have the ability to soft proof, pick a rendering intent, make print specific edits based on that etc.
Robust is a subjective term, preferred by consumers is vague (I'm a consumer and a photographer). PMC isn't robust enough to allow the capabilities I've outlined above. For me and others who can speak for themselves as either or both photographers and/or consumers.
If you want profiled printing to work, you better be prepared to spend a lot of time at each update of the OS or PS.
FUD! Epson supplies a host of ICC profiles, some better than others for their papers. 3rd party paper manufacturers can do the same.
With your logic, soft proofing isn't worthwhile (perhaps to you) because there's an extra step involved. Ditto with editing images or for that matter, exposing your captures correctly.
For cell phone users, and perhaps you consider yourself that kind of photographer, yeah, stick with PCM and any or all 'auto' corrections or anything else to print your photos. For pro's, not so much.
