I think these are all more efficient costly signals than frugality, but my impression is that they tend to be regarded by people (both inside and outside EA) as worse signals of altruism, and I’m wondering why that is.
(This reply addresses only some of your bullet points) If someone works crazy hours, that could be for altruism, but it could also be for higher status. Many people in the private sector selfishly choose to work long hours to be promoted, so it wouldn’t be that surprising that in non-profits people would as well, even if the monetary payoffs were lower.

(Obviously people can donate money for status reasons too).
