I don’t know how it would apply to painting minies. but there is definitely starter gear, which is better than ‘pro’ stuff - just by being friendly.

i climb and now that i am a bit better i use shoes about 2 sizes too small and have a pretty aggressive arch. bouldering in them is comfortable and i like them. but if i had them as my beginner shoes - i would have quit because that just hurts if you are not used to it. so i do see a benefit in beginner gear, even if you will eventually outgrow it.
