Currently, the API is not delivered to users since there is no agreement on
how to do it. For example the features that Fernando mentioned are not that
complex to code but hard to find an agreement on for the command-line
flags. Therefore, the possible annoyance of users is solved by not giving
them a choice at all, They simply cannot use the API, therefore they will
also not have to change it. By delivering something as experimental, the
users get a choice: They can use it and accept that they might have to
adapt or they can choose not to use it and be in the same situation as if
we did not deliver the API at all. Basically, we will provide additional
value to early adopters, unblock our development (the code can be written
already) and once there is an agreement on the final API, only small
changes would be necessary if at all. Therefore, adding experimental
features seem to be an overall benefit.
