Just as a point of correction, there is an automated way to deploy AODH 
The AODH project is, and has been, well represented by the 
OpenStack-Ansible community for some time. The role and playbooks were 
created back in Liberty [0] on Oct 7 2015 and has been part of our 
integrated gate since it's acceptance into the core OpenStack-Ansible 
project. Recently the "os_"aodh role has been split out into its own 
repository for use as a stand alone role. The OSA role can be found 
here: [1]

While I also can not speak to the intentions of others I will say I've 
never felt the need to burden other communities with deployment code for 
a given service because its generally not part of their development 
workflow. When I've been working on a service and needed things from the 
community developing that service I've reached out to them directly. As 
someone working on deployment code its been been great to get additional 
developer feedback from folks outside of our community; this is 
something everyone in the OpenStack-Ansible community is encouraged to 
do for all of the services we support. External interactions with other 
communities have been invaluable and greatly improved our project. All 
that said, if PTLs are looking to get their project contributors 
involved the various deployment projects I'm sure the additional input 
and access to resources would be greatly appreciated.
