If found two files with the name gpio.h which are located

1) ~esp-idf\components\driver\include\driver\gpio.h
2) ~esp\esp-idf\components\esp32\include\rom\gpio.h

In the SDK the two of them are clearly identify. e.g. in ~esp\esp-idf\components\driver\sdmmc_host.c
I found it however very dangerous. Maybe the less used should be renamed.

I made some systematic analysis and found that many files are doubles, often same name with different content, I give here the full list as completion of this post. Note files and repository are alphabetic sorted.

What's your reasoning to think this is 'very dangerous'?
