Word for the opposite of a feature in software development. An unwanted feature

I'm wondering if there is a word for a software feature which is not wanted and negatively impacts the software/business using it?

In my mind is not a bug as a bug is where something doesn't work as intended. In this case the "feature" functions as intended, it is just that its intent is misguided and in practice it is problematic for the business and we'd rather that users don't use it.

We would have the "feature" removed from the software, but would it still be considered a feature until it is removed? In my mind for software, a feature is inherently a positive thing. Or am I mistaken?

Example sentence:

Can you please remove the ability to do XYZ, it is a [word-for-negatively-impacting-feature]?

It is a design bug - a bug by design. It is sometimes also called a misfeature. That is, it is intentional, part of the design.

(Something that was overlooked at design time can also be called a design bug, however, and this includes a feature omission.)

Such a characterization is opinion-based. Typically the organization responsible for the product, or at least its designers, will not call it a design bug or a misfeature. Instead, they will pitch it as being a feature.

Misfeature is sometimes used for deliberately introduced features that are bad ideas. While mainstream dictionaries have

• archaic: a bad or distorted feature (MW)

Wiktionary has

• An undesirable or incorrect feature.

  • 1818, John Keats, The Human Seasons

    He hath his Winter too of pale Misfeature, / Or else he would forego his mortal nature.

  • 2003, John Ray, Maximum Mac OS X Security

    This may not appear to be a critical misfeature, and in fact I have on occasion come to rely upon this unintentional archive of data to recover the data.

which I've come across quite a lot in software and engineering sense.

To a native speaker it's easily understood from its components:

• mis--: bad/wrong/erroneous
• feature in the normal software sense

It's particularly useful for deliberate or well-intentioned features that actually make things worse.

You could use words like nuisance, inconvenience, hassle or menace to refer to such an unwanted feature.

Can you please remove the ability to do XYZ, it is a nuisance?

Although these words are not technical, and in some formal applications inappropriate, they convey the intended meaning when used in this context.

The meaning of nuisance in Oxford Dictionaries is

A person or thing causing inconvenience or annoyance.
