ThinkPad T480s & thinkpad_acpi.ko

Hi! I just found out that thinkpad_acpi.ko is not automatically loaded
on new ThinkPad T480s. Is there any reason for it? Manually calling
modprobe thinkpad_acpi is working fine, but I would expect that it
should be loaded automatically.

Here is dmesg output after loading it manually:

thinkpad_acpi: ThinkPad ACPI Extras v0.25
thinkpad_acpi: ThinkPad BIOS N22ET34W (1.11 ), EC unknown
thinkpad_acpi: Lenovo ThinkPad T480s, model 20L7S03000
thinkpad_acpi: radio switch found; radios are enabled
thinkpad_acpi: This ThinkPad has standard ACPI backlight brightness control, supported by the ACPI video driver
thinkpad_acpi: Disabling thinkpad-acpi brightness events by default...
thinkpad_acpi: rfkill switch tpacpi_bluetooth_sw: radio is unblocked
thinkpad_acpi: Standard ACPI backlight interface available, not loading native one
