Why is there a mismatch in the version of Qsys TCL package when exporting system as Qsys script(.tcl)?

Description

You may see the TCL version 16.0 needed in the script when you export it in the Quartus® Prime Software Standard Edition version 16.1 and later.

This is the line from the Tcl script:

          package require -exact qsys 16.0

This is the correct behaviour and the version does not need to match.
