Solid - not needed translated strings?

[Marius P]

Hello,

>From what I see, the KDE Framework 5 Solid does not need translations for
the strings:

#~ msgctxt "Solid::DeviceInterface|A pointing device"
#~ msgid "PointingDevice"

#~ msgctxt "Solid::DeviceInterface|A keyboard"
#~ msgid "Keyboard"

#~ msgctxt "Solid::DeviceInterface|Internet Gateway device type"
#~ msgid "Internet Gateway Device"

And a number of strings like:
"msgctxt "Solid::DeviceInterface|<something> device type""

Question 1: are those strings used/needed?
Question 2: if they are not used/needed, can I remove them?

Thanks.
