BTW, I always question the wisdom of putting environmental sensors on the main board because what good does it do to know the humidity and temperature in an enclosed box ?
My personal preference is to purchase bits as I find a use for them. You will still need other bits after you install this HAT so it isn't a solution to cover everything at once. Do you require an audio driver - I don't as my system is locked away and I talk to it via wifi. Do you need GPS - I have it but don't need it because my existing boat GPS data is fed to the pi. Environmental sensors, as noted above, are useless in an enclosed box, IMU .... don't know why I would want it, UPS - good feature but readily available for cheaper.
In other words, this is a very personal decision. You might want all the sensors and options and it might be worthwhile for YOUR application.
Valid, all valid
there are definitely features I like about the board, but as you say it does have limitations, sensor placement being the most obvious.

For this reason I go a total different way. I use virtual com ports for everything. This means each sensor and actor do as it possible his things with an esp8266 that I flash and push the data via WiFi to the raspberry pi. At least I install Alexa Echo and Google home on the raspberry pi. EG at the moment I experiment with sonoff.
How I do it you find in my blog at http://donau-grundel-schiff.de
As soon it runs I try to bring it directly in signal k. It's the part of solar. Sorry for the English there. My mother language is german.
