It might seem that way, but the issue is not really that simple. Moodle Users may prefer this functionality, while users of other packages might desire pre-configured SOAP functionality, and yet other users might want even other extensions. Each extension installed increases the memory footprint of PHP, and the larger, and more bloated, PHP becomes, the less RAM is available for processing. There have to be limits and compromises made.
Our philosophy is that we should provide a solid, functional, yet lean, installation of PHP that meets the needs of the largest possible cross-section of users and uses the least possible resources in doing this. Every suggestion to add a module/extension is evaluated with regard to how well adding that module/extension meets this criteria.
All that said, you can certainly post this as a suggestion in the panel, and it will be added to the suggestions already there where users can vote for/against it, and be considered by our developers/admins.
This is how many features get implemented, and if you feel strongly about this I recommend you make that suggestion in this way. Not every suggestion can be implemented, for a variety of reasons, but the suggestion system in the panel gives it is best chance of being seriously considered and possibly implemented.
