It's needless.
I think it should never be increased. And for me, the alteration is a disaster.,
You are 100 right, increasing the number of BTC in supply will not provide us some good results. As it will provide an opportunity to BTC haters to spread bad words about it. Besides haters, it will hurt the feelings of miners, validators, btc users and those companies which had trusted the scarcity factor of BTC and invested millions of dollars to build a fortune. This will looks like a scam or a phishing scam in which people will began to think crypto really is a scam as the king of all cryptocurrencies has scammed us.
Overall, you are right about it will damage BTC reputation and in my thoughts it will damage the reputation of all those who invested in it and trusted the mechanism. But you know what, the supply of BTC has been already wrote means it is no more changeable. According to many studies it has made sure that BTC is totally scarced (mean have limited supply).
And there is one more thing, which is we might not have to worry about it but maybe our next generation have to because they are the ones who will face this disaster, if any happens. But I believe BTC developers must have some surprises to amaze us in the context of this question.
