For a start, you have to decide how to weight the different groups of

For an application which is designed for end users and will be in a
permanent state of flux, dealing with revisions to the language or its
standard libraries are likely to be a small part of the ongoing
development effort.

For libraries or middleware which need to maintain a stable interface, or
for code which needs extensive testing, documentation, audits, etc, even a
minor update can incur significant costs.

Users in the latter group will prefer languages with a stable and rigorous
specification, and will tend to view any flexibility granted to the
language implementors as an inconvenience.
