Exactly. But there's no intention to stop building them as modules.
Imagine you build a kernel that's supposed to run on multiple
different platforms (like x86), you really don't want all DRM drivers
built-in. Instead, you load the correct driver during boot-up. To
still provide early graphics access, we use simplefb.

Note that there might be legitimate reasons to make DRM drivers
built-in. But at least general purpose distros avoid that.
