Full-Span Barline at End of System

Your idea

FEATURE
There is an older engraving tradition of a full-height barline at the end of each system.
Example Barline at End of System.pdf

PURPOSE
This is a much more effective visual tool than a system-break symbol, especially in vocal music where the separated barlines of each voice staff make finding the beginning of the next system confusing.

CONCEPT
There is already a style option for the "Barline at start of multiple staves," so I'm curious if this same feature could be adapted into a "Barline at end of system" or "Barline at end of multiple staves" checkbox. Nevertheless, I wouldn't be surprised if an implementation ends up being considerably more complex due to technical quirks.

Problem to be solved

MOTIVATION
Although this engraving style is perfectly achievable with simple workarounds, it can become cumbersome to implement if the layout of the score changes (barlines are reset when this happens), or if the measures reflow, necessitating different barlines be extended or reverted to default. This would be especially helpful with larger scores possessing many staves.
