Exactly. There's no technical reason for WSPR to require a "linear" transmitter, and to modulate it via 'audio' from a soundcard. It's a frequency shift keying mode with no amplitude shaping (unlike PSK31 & Co).

Before I am corrected WSPR is possible but only via some jiggery pokery using a four direct frequency shift pattern. Clever Johan SM6LKM has cracked it.
