The reason I was looking at this is I want a package installation tool 
to warn if the PKG_OPTIONS doesn't match the PKG_SUGGESTED_OPTIONS of an 
existing installed package if requested to "update" it. In other words: 
warn if replacing a custom package. I can't be too specific since there 
is no easy way to know if the option names had changed and newer package 
may provide the same features even if options changed.

I realize I had posted a similar email about this earlier this year too:
