GDM shows only GNOME and GNOME classic after boot/reboot

I’m not on nvidia:

[csteinforth@E14 ~]$ lspci -k | grep -A 2 -E "(VGA|3D)"
00:02.0 VGA compatible controller: Intel Corporation UHD Graphics (rev 02)
	Subsystem: Lenovo Device 5079
	Kernel driver in use: i915

But on Arch wiki I found this. So I added i915 to the MODULES section in mkinitcpio.conf. After regenerating initramfs and reboot the three options (‘GNOME’, ‘GNOME classic’ and ‘GNOME on Xorg’) are there in GDM, and GNOME session is on wayland May switchting to early KMS start have any side effects?
