If you ask if someone else has noticed this two or someone can explain what options has to be used for this then you are at the right place…
To report this for 4.0 this may be a bit late and not best possible location because: FAQ #3.
Also since the developers already put this into blender itself:
Blender → Help → Report a Bug
this will also include your OS, Graphicscard, Blender version, etc. . See also:
https://developer.blender.org/docs/handbook/bug_reports/making_good_bug_reports/
Please try to describe as precise as possible and also maybe try to make a simple reproduceable blend file. If there are too much questions to clarify then this only spend (“wastes”) time… if you know what i mean 
Also: be sure to have read the docu about parenting; especiallly vertex…
Because… there is a great possibility that this would be noticed already in the two years since the release of 4.0 in November 2023 !?
(I did not used the vertex parenting feature myself yet at all… so IDK…)
( You have done this for almost two years now ?? )
Happy blending.
