SuStel:

Maybe for the same reason the English didn't use nearby?

hmm.. is there a rule that in be-verbs used as adjectives someone can
place the {-Ha'}, or is this sentence from paq'batlh an exception ?

and remind me of something.. in verbs used as adjectives, we can have
the {-qu'}, right ? but can we have the {-be'} ?  In the above
sentence could there be {Daq Hopbe’Daq qa’chaj nejlI’ qotar Qempa’QeH
je} ?

We've seen three of the four rovers used as suffixes on adjectival verbs. -qu' appears in The Klingon Dictionary (section 4.4) and is explicitly allowed. -be' first appears in Conversational Klingon in the section on counting as wa'maH yIHmey lI'be'. -Ha' first appears in Klingon for the Galactic Traveler as Duj ngaDHa' in the section on slang. Each type has been used more than once.

Clearly, -qu', -be', and -Ha' are all allowed on adjectival verbs. I don't think we've ever seen any other suffixes on such verbs.
