In truth, the phonology is unimportant for making a loglang. For making an artlang or an auxlang (auxillary language), phonology is very important—but not for loglangs. It’s more of an aesthetic choice.
I don’t see any reason to think of strict categories like auxlang and loglang that are mutually exclusive.
The notion of a loglang means that you want your language to fulfill certain criteria and are thus willing to make it a bit harder to learn, but that doesn’t mean that ease of learning the language is irrelevant.
Lojban itself goes through exercises like making it’s terms resemble existing words to be easier to learn.
