Thanks for the replies. A clarification or 2.

I should probably have written “Should I be accumulating miles in additional programs (“orphan” programs to me) just to accumulate miles, without any plan as to how to maintain and/or use those miles?”

And I’m not a complete miser. In the past few years I’ve redeemed miles for 5 different international premium awards. I wanted to imply that I don’t spend them as soon as I earn them and I want to have enough so that I don’t have to worry about award inflation or how many I need for a desired award.
