Does using mobile shaders on PC have any drawback?

Question

Of course it's faster. But why did Unity make separate shaders instead of focusing on the absolute performance? Mobile has vertex lit while legacy also has vertex lit, there are many diffuse shaders, legacy has unlit, mobile has unlit, and there are group of unlit shaders. Also "mobile unlit(supports lightmap)" what the heck does this mean? Unlit means nothing to do with lighting doesn't it?

Its always a trade off between Features (Visuals) and performance. Yes you can use the mobile shader on PC but you will loose a lot of features compared to the standard shader.

Unlit in this case means does not use real time lights. The "normal unlit shader did not even support lightmapping so they created a shader that does support lightmapping. It all depends on what you need.
