A feature called like "Passthrough": If a skill is in developer mode, only local (Alexa linked to the same account of the skill author?), forward any request to a predefined intent "Catch all", and if reply false, continue with the normal Alexa parser flow. For hobbyist and local/personal use.

Reason:

In my home, i have a custom home-automation system command(string)>response(string), with a Telegram bot (called "Memole"). Commands like "Temperature", "Power report", "Activate garden" etc.

I have a lots of Alexa and i develop (note: for myself only) a Custom Skill and a Home Skill.

Now, for the Telegram equivalent command "Temperature" (1 word), i need to tell:

"Alexa: ask to Memole Memole about Temperature".

7 words VS 1 word. Claiming that my wife remember it is utopian.

Details:
"Alexa": ok, mandatory Alexa activation.

"ask to Memole Memole": Invocation name must be two word.

I understand the marketing rule, but it's a sad restriction for personal/hobbyist, not related to publish the skill in a store. A simple "if skill is private, allow one word invocation name" is a dream.

"about Temperature": Again, another big restriction. LITERAL utterance "*" it's not permitted anymore, so i need to write one thousand "about {SearchQuery}", "for {SearchQuery}", "the {SearchQuery}" all with the same Intent, "forward {SearchQuery} to my system".
My system already parse hundred of commands, it's unacceptable to recreate every of them in the Alexa Developer Console.

It's frustrating that i cannot IN MY HOUSE say a simple "Alexa, Power report" to obtain the output of my system (a mix of info from photovoltaic, Tesla Battery etc).
