Pretty much. I live in an area where there aren't many choices. I have soft water falling from the sky, and liquid rock coming up from the ground, and not enough of either to spare for RO, which we only use for drinking/cooking. I use a mix of the 2 sources for all my tanks to achieve the chemistry I want. Basic box store filter cartridges filter out most of anything that makes it past the roof washer. No problems with this setup. The bird poop conspiracy makes me laugh...where do fish live in the wild? I am certain that my water has fewer pharmaceuticals, chlorine-derived carcinogens, and probably agrochemicals than any municipal water supply. All sources carry some risk; do what you are comfortable with and works for you.

I live in uk in the countryside and built my own lean-to roof to catch rainwater . A clean sheet of pvc ,
I used it and on the 3rd water change I had a massive green water outbreak ,
That was the only thing I did different to my tank for over 2 years so it was obvious it was the rain water ,
Use it at your own risk , its probably hit or miss but like someone previously said ,
Would you drink rainwater ??

Where there's a will there's a way
