This topic is returning very often, and Okrand seems to be "not at all picky about that." (email to the mailing list from loghaD, 11/16/14)

The creator of the language hardly needs to worry about whether words he can make up at the drop of a hat need to have spaces in them.

Okrand is also more concerned with spoken Klingon than written. His transcription system is just a description of pronunciation, and you don't usually pronounce spaces between words. So when pronounced, HoDlupDujHomquS is identical to HoD lupDujHom quS chair of the captain's shuttlecraft.

But that doesn't make the long constructions single words. That phrase, however it's pronounced, consists of three words. If you want to specify that you meant the chair of the captain's red shuttlecraft, you can just stick another word in there, whether you originally thought of the phrase as one word or three: HoD lupDujHom Doq quS. If HoDlupDujHomquS were really one word, you couldn't do that.

Spaces are just punctuation. Okrand has never been concerned with punctuation. Punctuation is part of a writing system, and we know very little about the Klingon writing system, so we know very little about their punctuation. How we punctuate in a transcription system that has nothing to do with any actual Klingon writing system should be largely irrelevant.

However, if everyone feels justified in making a big stink about how you have to capitalize all the letters that Okrand capitalizes, even though the system looks ridiculous, I don't see what leg you have to stand on to want to eliminate the spaces that Okrand uses consistently throughout his transcription system. Basically, if we are to start eliminating spaces because we feel like it, then we should also be able to eliminate the silly capitalization of the transcription system. There's certainly enough call to do so.
