scope of scheduler.c and trx_sched_*

I notice that apparently osmo-bts-trx is the only caller of the trx_sched_* API, yet it is implemented in common/scheduler.c and compiled to libl1sched.a. Is osmo-bts-trx really the only caller? Also in osmo-bts-trx, the "trx" to me means SDR, like B200. But any BTS has one or more TRXs. So why isn't it osmo-bts-sdr? That's why I thought: maybe trx_sched_ is for all BTS models?
