As to why \intop looks so weird, I have no idea. If you add \usetypescript[modern-base] \setupbodyfont[modern] it will work ok. Cambria Math also results in two different heights of the operator depending on whether limits are there or not. It might be a bug somewhere in virtual font setup of LM.

The message were delivered to the subscribers. You can also check that in the archive [1]. We just have to be patient.

All the symbol mappings are defined there. Please feel free to complete the table (it is a boring and time consuming process, and I have only managed to cover about half of the table). Regarding your mappings, IIRC -> etc are mapped to \rightarrow etc, (not \xrightarrow). We can talk about including style variants for the mappings.
