What values will you be storing in trac.ini? Are the values currently
stored in the database?

Here's an example:
>>> from trac.env import Environment
>>> from trac.ticket.model import Type as TicketType
>>> env =
Environment('/Users/rjollos/Documents/Workspace/trac-dev/tracenvs/proj-1.0')
>>> for t in TicketType.select(env):
... print(t.name, t.value)
...
(u'defect', u'1')
(u'enhancement', u'2')
(u'task', u'3')

Yeah #11148 is sorely needed, and revisiting that is high on my priority
list.
For now, I think you'll have to use IRequestFilter:
https://trac.edgewall.org/wiki/TracDev/PluginDevelopment/ExtensionPoints/trac.web.api.IRequestFilter
That won't notify you in the case that the Ticket Type is added using
trac-admin. I don't see a way to handle that scenario, short of
implementing #11148.
