The original in-universe reason for why more T1000's were never mass produced makes the original T1000 even more badass compared to the Terminators that came after (in both canon and just as movie villains).
According to the novelizations, the original T1000 in Terminator 2 was a prototype that basically had a mind of it's own (or more like, thousands of nanobot minds working together to form an autonomous creature), unlike other terminators that were in read-only mode. Skynet feared that they wouldn't be able to control the T1000 model and that the self aware model would go rogue and do their own thing independent from their mission, which might include killing Skynet, which had Skynet reluctant to ever actually activate the T1000
The original Terminators didn't feel remorse, but they also didn't feel pleasure or anything else.
The T-800 completing a termination was like

And that difference terrified Skynet
I think we get a bit of that enjoyment-beyond-the-mission streak in T2, as the T1000 develops a sadistic personality, waves a finger at victims, and seems to enjoy killing and observing its death blows
So even with fewer "features" than the T-X or whatever, the T1000 was actually more dangerous because it had the capability of becoming sentient without a flip being switched, developing a personality, and motivations independent of Skynet, and Skynet had no idea what would happen if they activated this new creature of their creation. They only did so out of desperation. But Skynet feared that thing
