topic/jsiwek/while has an implementation of a general purpose 'while' loop.  If one wants to hack around the current limitation of only looping over collections, they're going to do it (e.g. recursion), so why not just provide a more convenient way instead?  The mess you have to write to work around the limitation may be more error-prone than just providing a simple while loop.

An alternative to adding 'while' to the language might be to allow "for ()" to be an unbounded loop and force the author to put the necessary break/return conditions in the body.
