Yes, it's rubbish and was obsolete before the first Kindle was released. Predates Kindle.
Only K1, K2 and all variations of DX or DXG need old mobi/KF7. Everything else can use azw3/kf8

Old Mobi /KF7 /azw
No embedded or user fonts.
Only one each of Serif, Sans and Monospace fonts.
Basically only Western Latin-Roman text with a few Greek and Scandinavian letters.
Only Left to Right text
No CSS (limited inline styles)
HTML3
Obsolete even in 2000, 1st Kindle in 2007.
Only needed for Gen1 & Gen2 Kindles.

azw3 /KF8
Embedded fonts (and also user fonts on many Kindles).
Any language (though UI and Dictionaries may be only English on older Kindles), though might need the font embedded to work.
Left to Right or Right to Left text
CSS
Subset of HTML5
Similar to epub2 and most content published on Amazon as reflowable novels is sent to them as epub.

Who MAKES a Kindle?

but AZW3 was announced as DEFAULT format in the lates update 8.6

amazon . they blocked my account for "unusual activity" and steal
all the books I bought together with money I paid
