Does esphome build to much?

ESPHome

while building for esp8266
I find this in the log

there are maybe more,
but I think I only need one of those lines,
Would it save space if not all are included?

You will find the code in the source files is #ifdef’ed for the platform so no space is consumed. If it were not, they would not even compile.
