Eepitch blocks vs. Org ":session"s

In a discussion on IRC during the EmacsConf 2023 I met a person who uses Org a lot and who had tried to use eev and eepitch a bit. (S?)he sort of said that:

• eepitch blocks are stricly less powerful than Org's code blocks, and
• that (s?)he couldn't see the point of eev.

That took me by surprise, and I spent the following days thinking a lot about that. Now, compare:

• eepitch blocks are strictly less powerful than Org's code blocks,
• eepitch blocks are similar to Org ":session"s,
• eepitch blocks don't parse their outputs, and don't export them back,

with:

• Org and eepitch can be used together - even in the same file,
• Org and eepitch induce different workflows,
• bare metal black box M-1 f8
