Any word of SAS-4 support from Broadcomm?

I have a Adaptec (Microsemi) HBA 1200 (PCIe 4 SAS-4(/NVMe/SATA)) and this page:
   https://storage.microsemi.com/en-us/support/sas/sas/aha-1200-8i/

references a "SmartPQI 64-bit Driver for FreeBSD 11, 12 & 13". Has anyone
tested that driver? The hardware seems to work fine on Linux. One new feature
(that I had not seen previously) is that the HBA itself presents a SES device
internally (i.e. it can't be seen by on another initiator connected to the
same expander).

 From the machine with the HBA 1200 installed I see:

# sg_ses -af /dev/sg3
   Adaptec   Smart Adapter     0107
   Primary enclosure logical identifier (hex):
Internal Device  [0,-1]  Element type: Array device slot
   Enclosure Status:
     Predicted failure=0, Disabled=0, Swap=0, status: OK
Controller Temperature Sensors   [1,-1]  Element type: Temperature sensor
   Enclosure Status:
     Predicted failure=0, Disabled=0, Swap=0, status: OK
     Temperature=35 C
emc_1414_int:0:0:Inlet Ambient   [1,0]  Element type: Temperature sensor
   Enclosure Status:
     Predicted failure=0, Disabled=0, Swap=0, status: OK
     Temperature=29 C
emc_1414_ext1:1:1:Chip ASIC      [1,1]  Element type: Temperature sensor
   Enclosure Status:
     Predicted failure=0, Disabled=0, Swap=0, status: OK
     Temperature=35 C
emc_1414_ext2:2:2:Vendor define  [1,2]  Element type: Temperature sensor
   Enclosure Status:
     Predicted failure=0, Disabled=0, Swap=0, status: OK
     Temperature=30 C
emc_1414_ext3:3:3:Vendor define  [1,3]  Element type: Temperature sensor
   Enclosure Status:
     Predicted failure=0, Disabled=0, Swap=0, status: OK
     Temperature=34 C

So it has 4 different temperature sensors on the card! Those figures are with
a fan attached to its heatsink. Without that fan (and with no other air blowing
on that card), I have seen temperatures above 70C. So a fan is needed (as
MicroSemi recommend).
