Observability , in the vein of accessibility which has the silly nickname of a11y

This is all coming from stenography, it's a well established shorthand for long words: first letter, count of middle letters, last letter.

No, it cane from DEC https://en.wikipedia.org/wiki/Numeronym#Numerical_contractio...

It seems unlikely to me that stenography would use this style because they have better ways of abbreviating long agglutinative words.

Which is similar to i18n for internationalization and l10n for localization.

ironically that's not very accessible...
