Martin,
I am not suggesting this as a regular practice by any means. But I have
received images from time to time that are already in sRGB when given to us.
On occasion a client might say that the reds or greens just aren't quite
vibrant enough, for example. We have found that if converted first to a
larger color space (ProPhoto for example), we can sometimes "cautiously"
tweak the image a bit to improve the image. Of course baby steps are what is
critical here, or as you say, you will end up with a worse result than when
you started.

What percentage of colour corrections and adjustments automatically
*benefit* from being in a larger colour space?
And what percentage of the small amount that *just might* would
benefit from choosing ProPhoto when the original was 8 bit sRGB?
If you are talking about shots where the models end up with faces the
colour of radiation burns and have those tell-tale deep red contours
as the skin darkens towards a shadow then you are probably right.
But they probably started life as natural looking sRGB images before
being converted to AdobeRGB (or larger) and adjusted by people who
didn't know what they were doing and couldn't see the damage they were
causing on their sub-standard monitors.
Invariably they are same people who also don't realise that they can't
then convert to smaller RGB working spaces without making the damage
they've done look even worse than it did in their wide gamut space...
