The RPI4B 8GiByte context I have mentions twsi in
the sysctl output:

# sysctl dev.iichb
dev.iichb.0.debug: 0
dev.iichb.0.rise_edge_delay: 48
dev.iichb.0.fall_edge_delay: 48
dev.iichb.0.clock_stretch: 64
dev.iichb.0.frequency: 100000
dev.iichb.0.%parent: simplebus0
dev.iichb.0.%pnpinfo: name=i2c at 7e804000 compat=brcm,bcm2711-i2c
dev.iichb.0.%location: 
dev.iichb.0.%driver: iichb
dev.iichb.0.%desc: BCM2708/2835 BSC controller
dev.iichb.%parent: twsi

(Not that I know the implications, if any.)
