(Query) status of shift-select-mode

[akashpal-21]

Dear Xah,

On Nov 29,2021 via commit ab84cd9 shift-select-mode was set to nil.

Isn't it more in line with other editing applications to use the shift key for selecting texts?

In emacs 28, a new option 'permanent was added , this behaves more in line with how set-mark operates.

Is there any rationale as to why it is set to nil as part of xah-fly-keys mode

Would you be inclined to add a custom option in line with xah-fly-use-shift-select to set this option?
