Can't we get some from ConfigEntityStorage::MAX_ID_LENGTH and use for machine names? 32+16=48 would be sweet spot IMO and ConfigEntityStorage::MAX_ID_LENGTH become 166-16=150
Currently the maximum length of machine names is limited to 32 characters.
See this change record: Entity type and bundle machine names have a maximum length of 32 characters →
It is a limit that is rather short and easy to hit when creating new content-entities and fields.
Cropped machine names show up in config-exports, so there are real artefacts of the 32 character limit in many projects.
I don't know the exact reason for 32, but I guess 8 or 16 was too short and higher numbers felt unneeded and possible lead to slower database performance.
I can't exactly tell if there are performance implications, but an increased size to 64, 128 or even 512 characters would be better IMO.

Not going to close the issue, but that's not really possible.
We didn't pick that number just for fun. field config entity IDs consist of entity type + bundle + field name. The max id length of a config entity is 166 ( \Drupal\Core\Config\Entity\ConfigEntityStorage::MAX_ID_LENGTH). entity types and bundles can each be 32. so 32 each gives you ~100 for fields. and bundles (node types) can't be longer than 32.
Field names then again are referenced in several tables, for example comment.
I strongly recommend to keep them as short as possible. Longer field names need to be hashed, which IMHO complicates the database structure. It's not really a performance issue, more a DX issue if you ever need to do some queries and things there to investigate things. Much easier to find the right tables then.

It's likely this issue predates Contrib.social: some issue and comment data are missing.
