The only simi-permanent change Poot makes to the phone is that it puts the su binary at "/system/xbin/su". It doesn't change any settings or build props, it doesn't install or remove any other apps, and it doesn't change any attributes for any files/directories/partitions. I want it to do only the minimum to to allow you to get root access.
On the 4 or 5 models now that we have tested Poot on, the presence of that su binary by itself is not enough to brick the phone. And even installing superSU/superuser didn't hurt them. It was more likely caused by something you did with your newfound control of your phone that broke it.
