I have to go out of my way to find a real image color that is outside
AdboeRGB. Especially in historic images...

Its much larger, and if I can't find colors I'll lose in AdobeRGB, then the
advantage is practically nil, while the disadvantages are still there. The
disadvantages include the fact that its not a stock Photoshop space, that its
*much* larger than a monitor space, so if you are truely getting colors way
out there, they won't show on screen anyhow (also true to a much lesser
extent with AdobeRGB), and that it really should be used *only* in highbit,
as it is so large that is will stretch the 256 levels of an 8 bit/channel
file far too thin, and cause potential banding or loss of detail. You could
make a case for it in a three tiered workflow where EktaRGB/16 bit as your
archival version, AdobeRGB/8 bit was your quality working version, and
sRGB/8 bit was your web version, but its more effort, more problematic, and
won't show much improvement in a practical sense.

Those are the factors that would lead me to archive AdobeRGB (perhaps in
highbit) and use AdobeRGB for highend output, while using sRGB for web output.

You'll need to determine your own tradeoffs, but an AdobeRGB/sRGB workflow is
relatively simple, but should still offer the quality you need.
