Based on discussions in that github issue, and thanks to Camelid on github, the info message has been improved to this (updated):
info: using up to 500.0 MiB of RAM to unpack components
The issue clarifies the reasons why the message is shown by default, for the time being:
we wanted it visible in logs if anyone reported an issue which might be related to unpack RAM. We have had small system issues in the recent past
If you got here via a web search, see the issue and the documentation if you need to change the RAM allocation for unpacking, etc.
