Keyword separator limitation not backward compatible

[donc61415489]

Somewhere along the line, Lightroom imposed a new limitation on keywords preventing the use of either commas or spaces in keywords, because they now say commas or spaces are used as a keyword separators.  (What was the separator character when these characters WERE allowed?)

For years now, I have created hundreds of keywords using both commas and spaces to tag people by last name, first name and towns by city, state.  Do I now have to manually change all of those keywords to eliminate commas or spaces?

I would like Adobe to add more keyword separator options.  For example, "." and "/" can be treated as keyword separators when reading metadata.  Why are these characters not allowed as separators for keyword entry?

At least as far back as LR 3, commas have been the keyword separator in the Keywording panel and not allowed in keywords. If you tried to create a keyword with a comma, LR would complain. 

However, due to longstanding bugs, LR sometimes creates keywords with commas; e.g. when you import photos containing such keywords, LR doesn't alert you.

Spaces have always been allowed within keywords.

"...they now say ... spaces are used as a keyword separators. "

Where do you see that?

In preferences you have an option to choose comma or space as keyword separator.

Regardless of how long it’s been done that way, the need remains.

"In preferences you have an option to choose comma or space as keyword separator."

True, but comma is the default, and the choice of comma or space has always been there.

"For years now, I have created hundreds of keywords using both commas and spaces to tag people by last name, first name and towns by city, state."

Did you do this in another app and then import the keyworded photos into LR?  You could never have entered such keywords in LR.
