"public.mpeg-2-transport-stream" does not show up with "qlmanage -m"

[reggi]

I am trying to use QLStephen to show quick look for .ts files (public.mpeg-2-transport-stream).

I added a couple ofkMDItemContentType ids to the Info.plist.

For some reason all of the ones I added work / show up in the list (using qlmanage -m | sort) except public.mpeg-2-transport-stream.

<string>public.data</string>
<string>public.content</string>
<string>public.mpeg-2-transport-stream</string>
<string>dyn.ah62d4rv4ge81k652</string>
<string>com.netscape.javascript-source</string>
<string>dyn.ah62d4rv4ge80y652</string>
<string>public.shell-script</string>

My question is why do all of these show up, except for the public.mpeg-2-transport-stream?

com.netscape.javascript-source -> /Users/thomas/Library/QuickLook/QLStephen.qlgenerator (1.5.1)
dyn.ah62d4rv4ge80y652 -> /Users/thomas/Library/QuickLook/QLStephen.qlgenerator (1.5.1)
dyn.ah62d4rv4ge81k652 -> /Users/thomas/Library/QuickLook/QLStephen.qlgenerator (1.5.1)
public.content -> /Users/thomas/Library/QuickLook/QLStephen.qlgenerator (1.5.1)
public.data -> /Users/thomas/Library/QuickLook/QLStephen.qlgenerator (1.5.1)
public.shell-script -> /Users/thomas/Library/QuickLook/QLStephen.qlgenerator (1.5.1)

I believe this same issue is happening with qlcolorcode.

Apparently MacOS is not allowing this file type to be modified. It seems like no app can enable preview for ts files on Big Sur.

If we only could remove the transport stream assignment. How can this be completely locked by the OS?
