We don't need to reclaim the name. Still, `quadrature` is a bit too generic sounding for a function that shouldn't be relied on as a general purpose routine. The best reason for wanting to reuse the name is lack of imagination. If we don't reclaim the name, what would a good name be for an improved general purpose quadrature function with several methods? I suggested the verb `quadrate`, but I don't think that's commonly used. `scipy.integrate.integrate`? On Wed, Nov 29, 2023, 1:16 AM Ralf Gommers <ralf.gommers@gmail.com> wrote:

Hi team,
Thanks for the feedback on deprecating these functions. There was support for deprecating them, but also some concerns, so the plan has changed to the following:
- Deprecate `scipy.integrate.quadrature` (so we can reclaim the name for a more general-purpose function in the future).
This is something we try to never do. There are very few examples of us deprecating and then removing a name, and then reintroducing it with different behavior. There has to be an exceptionally good reason to do so, and I don't see one in the PR discussion (it's quite long, so I may have missed it). I can't even think of a potential reason, because the `quadrature` name isn't special enough that you can't pick a different name for whatever you want/need here.
Cheers, Ralf
- Introduce `scipy.integrate.gauss_quad` as an alias for `scipy.integrate.quadrature`, and point users to `gauss_quad` in the `quadrature` deprecation messages. - Mark `scipy.integrate.gauss_quad` and `scipy.integrate.romberg` as legacy functions.
We welcome additional feedback in gh-19510 ( https://github.com/scipy/scipy/pull/19510). Thanks, Matt

Hi Team,
`scipy.integrate.romberg` and `scipy.integrate.quadrature` do not reliably hit their target accuracies, and when they do, they typically require more function evaluations and take more wall clock time than `scipy.integrate.quad` (all with default settings). This is documented in https://github.com/scipy/scipy/issues/18574#issuecomment-1703320598, which compares the accuracies, function call counts, and wall clock times on a benchmark set of ~800 integrals with known analytical solutions.
gh-19510 (https://github.com/scipy/scipy/pull/19510) proposes to deprecate these functions, suggesting `scipy.integrate.quad` as a drop-in replacement. Please let us know your thoughts either here or in gh-19510!
Thanks, Matt
