Because it's a Russian name, and you were thus worried about possible 
connections to the Russian government?  No, it's an open format, meaning 
"(nested) Russian doll", alluding to its flexibility as a container 
format, and it's supported by a non-profit organization in France.  It's 
gradually overtaking .mp4 for storing AVC and HEVC videos, due to this 
flexibility, and because it's not patent-encumbered like .mp4.

If it bothered you, you could always use ffmpeg after MakeMKV to 
repackage your MPEG-2 MKVs into .mpg files without quality loss, since 
your DVD home videos presumably don't need to take advantage of the more 
flexible container.
