TYPO3 Core

If you need this feature, you can use https://github.com/WapplerSystems/Shyguy/ as long as there is no core provided solution.

Just asking before I put time into this:
Is this more a 'nitpick' or does a solution for "visible SHY/soft-hyphens in the TYPO3-backend" gets accepted into core?

See https://docs.typo3.org/m/typo3/guide-contributionworkflow/main/en-us/HandlingAPatch/Tips.html#decide-about-general-issues-before-fixing-nitpicks

• Is the issue itself relevant?
• Does the solution embed well in current development strategies?
• Is the architectural solution ok or is the patch just fixing some symptom instead of a different, maybe bigger problem?
• Does the solution contradict other patches we have in the same area?

Check out this approach via TCA custom eval-rule:
