That's a good question. I've assumed that the baseline was about
technology, and not the features of the technology. For example,
specifying HTML in the baseline presumably covers features such as
object, link, longdesc, etc, even though they may be partially supported
or poorly implemented. The media for the object might be another
technology in its own right, but I wouldn't have thought of specifying
the object element itself in the baseline.

I agree. A baseline is the set of technologies assumed to be supported
by and active in the user agent.

"Technology" is defined in the Glossary to include:
-markup languages
- programming languages (including scripting languages)
- style sheets (including but not limited to style sheet languages)
- data formats (including but not limited to image and media formats )
- APIs

How well the specific features of a given technology are supported by
available user agents and AT may be a factor in deciding whether that
technology should be included in the baseline; where there isn't really
a  sensible option (e.g., excluding HTML isn't much of a choice!), the
User Agent and Assistive Technology Support Notes section of each
Technique should provide information to help developers decide if a
particular technique/technology feature is suitable for their purposes.
